To (L7-l whom, may conc-ern A .I

lle it known that l, Jol-LN MULROY', a citi zen of the United States, and a Vresident of Jersey City, county of Hudson, and State of New Jersey, have invented a new and Improved Portable Oil Burner and Torch, of which the -following is a lull, clear7 and exact description. l

rllhis invention ielates to a heating device especially adapted tormelting snow. i

An object of the invention is to provide a simple and ei'ticient device which is readily portable :for directing iiames to melt snow, especially on railroads in connection with switches.

A further object is to proved a simple and eilicient device which is provided with suitable supporting means so that it can be set up to act as a flare on railroads when work at night has to be performed.

The invention is illustrated in the drawings ot which Figure 1 is a vertical section through the device;.

Figure 2 is a section on the line 2 2 ot Figure 1; u

l `igure 3 is an elevation of the device set un for use as a flare.

The form of the invention shown in` the drawings is a preferred torni, although it is.

understood that modiiications in the construction and arrangement oie the parts and in the character of the materials used may be adopted without departing from the spirit of the invention as set forth in the appended claims.

The invention in its general aspect comprises a nozzle in the form of a tubular membei` having a perico-rated opening. A funnel shaped member is associated with the end of the nozzle to coniine and direct 4the flames issuing rom'the nozzle. Within the tubular nozzle is a pipe the end ot which is disposed nea ot projecting air under pressure toward the end -of the nozzle. Oil under pressure is introduced into the nozzle at a point to the rear of the air pipe and is drawn toward the end of the nozzle by the suction of the air with which it becomes mixed adjacent the end ot the nozzle. This mixing of the air and the oil results in a highly inflammable mixture which when ignited and forced out under pressure, will form a llame of considerable length, which is directed and conthe end of thenozzle for the purpose.

irolled by the tunnel on the end oi. the noz,- zle. The pipes conveying the air and Aoil are ot orel'erably short. length and can be con` nected to flexible lioseso that the device can 'i be carried around from point to point at any desired distance from the source of air and oil supply.

The device is provided with tripod support wliichis readily collapsible When not in use and is capable when in use of holding the device inverted so that the llame can be directed upwardly to act as a flare to illuminate the vicinity at night. i .ln the drawings the preferred forni of the invention includes a tubular nozzle member j 10 the loiver end of which is provided Witlia perforated cap 11. lAround the lower end o't the nozzle member a cup-shaped support 12 is mounted and provided with air holes 13. This member 12 supports a iunnel 14.

lVithin the nozzle member is disposed an air pipe 15 supported in the nozzler member `by a cap 16. rEhe air pipe has a valve 17 therein. The loiver end 18 of t-he air pipe is disposed a short distance from the end of the nozzle member. A Tshaped head 19 embraces the middle portion ot' the nozzle member and an oil pipe 2O is connected thereto. A' valve 21 is disposed in t-he oil pipe. i

In order to support the device in anfinverted position for use as a ilare, I attach to the head 19a plurality of tripod legs 22 which in turn are connected by links 23 with a. sleeve 241 slidable alongtlie nozzle member. As shown in Figure 8 the legs will support the device. By. sliding the sleeve 21,1-, upward the legs may be collapsed to lie along the piping when not in use.

1n the operation of the device Isupply compressed air and oil under pressure through the pipes mentioned and by the valves can determine the proper mixture of the oil and the air. As the air issues 'from the. lower end of the pipe 15 it causes a suction in the nozzle member which draws the oil into the nozzle member in a finely divided condition and thoroughly mixes with the oil in the nozzle member just below the end of 'the pipe 15. The mixture pass-es through the p-erforations 11 and is ignited` forming' a. flame Which 'is lconiined and directed by the funnel member 111. This llame can be directed to melt the snow or ice around switches and the like or may be used as a iare when the device is disposed as shown in Figure: 3.y

vWhat' claim is Y A portableoil burner and torch I'Wliich comprises a` nozzle member having a perforated end, a iunnel-shaped flame and heateontrolling element mounted on said end and projecting tlierebeyond, said funnelsliaped element having'airpassages in vtits rear Wall around the end of the nozzle, an stir pipe extending intok the nozzle member to a point adjacent the perforated end, and an oil -pipe'opening into the nozzle member at a' pointl midway kthe length thereof, the

oilv and air being `mixed Within the nozzle member at a pointjust beyond the end'of the air pipe.

'and projecting there-beyond, said funnel-lk shapedelement having air passages in its rear Wall around the end of the nozzle, an

air pipe extending into the nozzle membery to a point adjacent the perforated end, and an oil 'pipe openingV into the nozzle member at a point midway the length thereof, the oil andV air being mixed Within the nozzle member at a point` just beyond theend of the air pipe, and a collapsibletripod Supporting means connected to the nozzle member and` adapted to support it in an inverted position when desired.
